在一些实施例中，请参阅图3，至少一所述散射粒子400为实心颗粒，所述散射粒子400的折射率与所在对应膜层的折射率不同。
所述散射粒子400为实心颗粒，则所述散射粒子400的折射率与所在对应膜层的折射率不同，增加所述光学膜300的光学结构的复杂性，利用折射率差异，增强显示光线在射向所述散射粒子400时的散射效果，将环境反射光线向四面八方进行漫反射，可以对环境光和灯影进行虚化，降低外界环境光影响，以增大光线的散射，改善显示光线侧视角特性，提高显示模组100的显示效果。

在一些实施例中，在显示模组100的出光方向上，包括所述第一气体的所述散射粒子400的数量密度逐渐增大。
在靠近人眼观看一侧，包括所述第一气体的所述散射粒子400的数量密度逐渐增大，可以减小与外界空气之间的折射率差异，从而可以使显示光线更顺畅射向人眼，减小显示光线折射损失。增加所述光学膜300的光学结构的复杂性，利用折射率差异，增强显示光线在射向所述散射粒子400时的散射效果，将环境反射光线向四面八方进行漫反射，可以对环境光和灯影进行虚化，降低外界环境光影响，以增大光线的散射，改善显示光线侧视角特性，提高显示模组100的显示效果。
在一些实施例中，所述第一气体可以为惰性气体，例如氦气、氮气等。在此只做举例，不做具体限定。空气中最多含量的成分为氮气，同时气体的折射率相近，相同条件下，第一气体的折射率与显示模组100外界空气的折射率相近，可以忽略不计。
在一些实施例中，所述腔体420内填充有第一液体，所述第一液体的折射率与所述颗粒主体410的折射率不同。
所述颗粒主体410包裹所述腔体420，在所述腔体420内填充第一液体，所述第一液体或所述第一气体的折射率与所述颗粒主体410的折射率不同，增加所述光学膜300的光学结构的复杂性，利用折射率差异，增强显示光线在射向所述散射粒子400时的散射效果，将环境反射光线向四面八方进行漫反射，可以对环境光和灯影进行虚化，降低外界环境光影响，以增大光线的散射，改善显示光线侧视角特性，提高显示模组100的显示效果。

在一些实施例中，请参阅图5，至少一所述散射粒子400包括颗粒主体410和至少一通孔430，所述通孔430贯穿所述颗粒主体410，所述通孔430内填充有所在对应膜层，所述颗粒主体410的折射率与所在对应膜层的折射率不同。
只需要将所述颗粒主体410利用所述通孔430进行贯穿，与所述光学膜300一同形成，制程简单，利用所述通孔430及所述颗粒主体410的折射率与所在对应膜层的折射率不同，增加所述光学膜300的光学结构的复杂性，利用折射率差异，增强显示光线在射向所述散射粒子400时的散射效果，将环境反射光线向四面八方进行漫反射，可以对环境光和灯影进行虚化，降低外界环境光影响，增大光线的散射，改善显示光线侧视角特性，提高显示模组100的显示效果。

所述光学膜300中最靠近所述显示面板200的膜层的折射率与最远离所述显示面板200的膜层的折射率大，可以使显示光线有散射效果。所述光学膜300中最靠近所述显示面板200的膜层的折射率与最远离所述显示面板200的膜层的折射率的差值大于或等于0.2，可以保证侧视角的显示效果，若采用多层膜结构，所述光学膜300中相邻两膜层间折射率差值小于0.2，层间折射率相差越小，则对于显示光线反射率越小，光损失越小，光透过率也会提高。
例如所述光学膜300只包括所述第一图案层310和所述第二图案层320，所述第一图案层310的折射率与所述第二图案层320的折射率之间的差值大于或等于0.2。例如所述光学膜300包括所述第一图案层310、所述第二图案层320和位于所述第二图案层320远离所述第一图案层310一侧的第三透明层330，所述第一图案层310的折射率比所述第三透明层330的折射率可以大0.3，所述第一图案层310的折射率比所述第二图案层320的折射率可以大0.15，所述第二图案层320的折射率比所述第三透明层330的折射率可以大0.15，以减小显示光损失，同时保证侧视角的显示效果，在此只做举例，不做具体限定。

在图6中，以第三透明层330为例代表位于所述第二图案层320远离所述第一图案层310一侧的至少一透明层，采用多膜层折射率差异，以在增强显示光线在射向所述散射粒子400时的散射效果，将环境反射光线向四面八方进行漫反射，可以对环境光和灯影进行虚化，降低外界环境光影响，增大光线的散射，改善显示光线侧视角特性，提高显示模组100的显示效果。
在一些实施例中，请参阅图7，所述光学膜300还包括位于所述第二图案层320远离所述第一图案层310一侧的第三透明层330、及位于所述第三透明层330远离所述第一图案层310一侧的第四透明层340；所述第二图案层320还包括靠近所述第三透明层330一侧的多个第三凸起331和多个第三凹陷332；所述第三透明层330包括靠近所述第二图案层320一侧的多个第四凸起341和多个第四凹陷342、及靠近所述第四透明层340一侧的多个第五凸起351和多个第五凹陷352；所述第四透明层340包括靠近所述第三透明层330一侧的多个第六凸起361和多个第六凹陷362；其中，所述第二图案层320的折射率大于所述第三透明层330的折射率，所述第三透明层330的折射率大于所述第四透明层340的折射率，一个所述第三凸起331与一个所述第四凹陷342对应，一个所述第三凹陷332与一个所述第四凸起341对应，一个所述第五凸起351与一个所述第六凹陷362对应，一个所述第五凹陷352与一个所述第六凸起361对应。
采用多膜层搭配多凸起和多凹陷进行共同配合，利用三组凸起与凹陷配合形成界面，可以在不损失过多显示光线透过率的同时，进一步增加所述光学膜300的光学结构的复杂性，利用折射率差异，增强显示光线在射向所述散射粒子400时的散射效果，将环境反射光线向四面八方进行漫反射，可以对环境光和灯影进行虚化，降低外界环境光影响，以增大光线的散射，改善显示光线侧视角特性，提高显示模组100的显示效果。
在一些实施例中，请参阅图7，由显示模组100的边缘至所述显示模组100的中心的方向上，所述第一凹陷312和所述第一凸起311的数量密度增大，所述第二凹陷322和所述第二凸起321的数量密度增大。以着重提高所述显示模组100的中心的侧视角改善，提高显示面板200的侧视显示效果。
